Today I looked at the ARM1176 manual about the interrupted part, it is very interesting. Write it down.
(a), first of all, say a bit PL192 vector interrupt Controller
An interrupt controller is a peripheral device used to handle multiple interrupt sources, and typically contains the following features:
1. Allocate one interrupt request input port for each interrupt source. Assign an interrupt request output po

September 2011 Time to make notes, then read interrupt subsystem code after doing a PPT, kernel version do not remember, hardware platform is Samsung's s5pv210.This part is mainly for the assembly and hard IRQ parts, the processing of SOFTIRQ after hard IRQ processing, and the processing of the lower half (tasklet/workqueue) are not involved.Agenda? Interrupts in ARM? Important structs? External Interrupt resources in s5pv210? Code flow? Kernel API? Interrupts in ARMThere are only two interrupt

During Modular programming, many projects adopt the module mode because it provides structured ideas and helps organize the growing code. Javascript, C ++, Java, and other object-oriented languages are different. It does not have the syntax for importing packages ,, however, the module mode provides a powerful tool for creating self-contained uncoupled code snippets. This is why many projects adopt this model.Now, let's get started. The module mode is actually a combination of the following mode

1 S5PV210 's Interrupt Controller profile s5pv210 is a cortex-a8-based Soc from Samsung, with an internally integrated interrupt controller connected by 4 arm primecell PL192 vectors Interrupt Controller-level ( Daisy-chain), each PL192 VIC (vectored Interrupt Controller) supports 32 interrupt sources, so it supports up to 128. S5pv210 used 93 of them. The so-called "vector" means that when the interruption occurs, the software can get the pre-set int
